single full-rack package that is only 178mm high (7 in). This level of density provides some impor­tant advantages. First, it reduces the amount of switching hardware required for a given ap pli ca tion.
Second, it provides high flexibility. The high density cards can be used with the special signal cards
to cover all your signal needs for a large application with one mainframe.

Switch a wide range of signals. The 7002 is fully compatible with all 7001 switch cards. From this
broad selection of 17 cards, you can assemble a switch configuration that will ensure signal integrity
and minimize errors. These cards allow the 7002 to switch DC signals from femtoamps to amps,
nanovolts to kilovolts, as well as RF and optical signals.

Analog backplane. The analog backplane used by the high density cards adds con fig u ra tion flex i bil­i ty and eliminates intercard wiring. For ex am ple, the outputs of a mul ti plex er card can be connected
to the row inputs of a matrix card. Or, the outputs of ten mul ti plex er cards can be con nect ed to form
one large 1×400 mul ti plex er. Intercard wiring is eliminated by using the an a log backplane to form
these configurations.

Faster Test Development

Unique channel status display. The interactive front panel display helps shorten the time required
to configure the 7002 and develop test software. The display indicates the open/close status of each
channel in the main frame. This information is very useful when programming the 7002 and develop­ing ap pli ca tion software. Knowing the channel status also helps to verify proper operation during the
debug phase.

Light pen programming. An optional light pen provides point and click pro gram ming from the
front panel. By selecting the desired channels or range of channels, the scan list can be built, matrix
patterns created, channels opened or closed, and patterns stored in memory. The 7002’s non-volatile
memory stores up to 500 com plete switch patterns.

Trigger Link

The Model 7002 Switch System is a 10-slot main frame that supports up to
400 2-pole mul ti plex er channels or 400 matrix crosspoints. The front panel
includes a unique in ter ac tive display of chan nel status for quick pro gram­ming. Scanning speeds of up to 300 channels per second are possible with
the high density switch cards. The wide selection of more than 30 different
switch cards makes the 7002 one of the most flexible switch ing main­frames avail able.

Reduce the Size and Cost
of Your Switching Application.

Up to 400 channels of 2-pole switching. A single Model 7002 mainframe
can accommodate up to ten 40-channel cards. That’s 400 channels in a

Ten-slot high density switch mainframe

Automatic card configuration. When the high density cards are installed,
the 7002 au to mat i cal ly configures each slot independently for the proper
card. The channel status display on the front panel adjusts to show each
card’s capacity and con fig u ra tion.

Front panel Info key. At the touch of a button, the operator receives con­text-sensitive, on-line information to help configure the system. This infor­mation is displayed on a 52-character alphanumeric display for clear and
readable messages. There is no need to refer constantly to the operator’s
manual. All information messages, operating instructions, and prompts are
available in English, German, and French. Just select the desired language
in the con fig u ra tion menu.

Programmable channel closure restrictions. The 7002 allows specific
channels to be locked out from closure. This restriction can be conditional
based on the open/close state of other channels or crosspoints. This capa­bility is useful to prevent certain signals from being accidentally connected
to high power circuits, for example.

System Throughput

300 channel per second scanning. The
7002 can scan through up to 300 chan­nels per second. This scan process can be
controlled by the internal time base of the
7002 or through external triggers. The scan
sequence is con trolled by what appears in the
scan list. The scan list can include channels,
ranges of channels, and memory locations.
This ap proach gives max i mum flexibility while
obtaining maximum through put.

Built-in Scan Control and Trigger Link. The
built-in scan control eliminates the need for the
computer to control every step of the test pro

scans. Trigger Link gives you access to six inde­pen dent hardware trigger lines on a single cable.
